what is NavIC in detail
welcome to g4gyans blogs
The Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, nāvik 'sailor' or 'navigator' in Indian languages), is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km (930 miles ) around it, with plans for further extension. An extended service area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east, 1,500–6,000 km (930–3,730 miles) beyond borders. The system currently consists of a constellation of seven satellites, with two additional satellites on ground as stand-by it accuracy is 1m or 3 ft 3 in (public) and 10 cm or 3.9 in (encrypted)
NavIC vs GPS: Which one is more accurate?
GPS or Global Positioning System tracks the entire globe and is maintained by the USA. The constellation requires 24 Satellites to be operational and has around 31 satellites in orbit. All of these are Geosynchronous Satellites, which is to say that they are not stationary in space with respect to the revolving earth. GPS also uses a single frequency band and this makes calculations a bit more complex.
However, the accuracy of the Standard Positioning Service available to civilians is 20 meters for both GPS and NavIC. This can be improved to 10 meters by combining data from cellular tower tracking – as is already a standard practice. Since the accuracy range is the same for the civilian arm of both navigation systems, NavIC might not result in a drastic improvement over GPS.
Having said that, the location accuracy is expected to see a noticeable improvement in “dense urban environments where geolocation accuracy tends to degrade.” Qualcomm assures more accurate location performance and faster time-to-first-fix (TTFF) in the NavIC supported region, especially in congested urban environment.
